| Instead of the circuit going: Boost -> T -> [Wastegate] and [Safety Boost -> MBC -> Suction] It is plumbed: A) Boost -> MBC -> T -> [Wastegate] and [Safety Boost -> Suction] Correct? Or is the safety boost gone altogether? B) Boost -> MBC -> Wastegate A would likely cause your wastegates never to open, and your boost would be high. B (No safety boost solenoid) should work as a pressure differential and cause your wastegate actuators to open at a higher pressure (assuming you have the MBC closed to some degree) Are you seeing '5psi' with the MBC fully closed?
